After the backup process completed, I turned off the old phone, connected the new phone, and selected "Restore" to restore the phone from the backup I just had created. After I waited through a reboot and confirmed a few more dialogs, I thought I would now have everything on the new device exactly the same way as I had on the old phone. But that was not the case…
When you do a backup of your PC or Mac and then lose your hard drive you would expect the machine to be exactly the same after you buy a new disk and run a restore operation, right? Especially you'd expect all settings and configurations to be restored.Apparently not so with iOS. To my great disappointment I found that for a lot of my applications the restore function only restored the app itself, but not any of its settings, especially not any login information. In particular, I had to manually reenter my account information into all of the following apps on my new phone:
- iCloud, iMessage, FaceTime, Find my friends
- MLB At Bat
- Disk Decipher
- and many more…
Now, in all fairness, I should say that in iOS at least there is a Backup/Restore function, which is completely missing in Android (unless you want to be adventurous and root your device). But I found it very surprising to be lacking in so many ways, especially with regards to app configurations, settings, and logins.
Luckily I don't have to complain about any actual data loss. With my calendar, contacts, and email all in Google Apps, none of those got lost. So this was more of a nuisance that cost me about an hour or two before I had my phone reconfigured to my exact specs and resetting all my soft-token apps.
But it would have been much harder to do, had I actually lost my phone or had it been damage, because removing 2-factor authentication from an account when you don't have the soft-token anymore is rather difficult and often only possible with lengthy tech support calls. It would make much more sense to allow full backup/restore functionality of your phone onto your computer - especially since you can encrypt your backups nicely with iTunes, so the information therein is rather secure.
Bottom-line: plan a couple of hours for your upgrade - especially if you use many apps…
